Alacritty: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
I've been looking for an extremely fast terminal emulator for many years. xterm has unfixed rendering bugs and is slower than molasses. I don't like urxvt's lack of memory management. st uses more memory than xterm (yep!).
Just saw Alacritty on HN and was determined to try it out.
What are your plans for older hardware? I'm currently using a couple of laptops from 2007-2008: a ThinkPad T43 and a ThinkPad T60. Unfortunately the Rust nightly you're currently using is broken on i686 (#126) so I can't test Alacritty on the T43, but it reported the error in the title on my T60 (which has a slightly better GPU, FWIW).
T43 specs:
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV370
OpenGL version string: 2.1 Mesa 11.0.2
OpenGL shading language version string: 1.20
01:00.0 VGA compatible controller: AMD/ATI [Advanced Micro Devices, Inc.] RV370/M22 [Mobility Radeon X300]
T60 specs:
Extended renderer info (GLX_MESA_query_renderer):
Vendor: X.Org R300 Project (0x1002)
Device: ATI RV515 (0x7145)
Version: 11.2.2

Yep, I realize these are kind of the "oh wow" of GPU land :) but I'm genuinely wondering what the best approach would be to support GPUs like these - I've been pondering making my own terminal emulator for a little while (as well as a 2D engine too, actually), but have absolutely no knowledge of OpenGL, Vulkan, etc.
"It would be impossible" is completely understandable; "it would require a nontrivial architecture redesign" also wouldn't be too surprising.

It's not impossible. I took a shortcut using a GL feature GL_ARB_blend_func_extended to make sub-pixel font rendering work properly. There are other ways to achieve this, and I think doing so would be reasonable for the project.
Alacritty's memory footprint is a bit high unfortunately. This will hopefully be improved in the future, but it's still early days in this area.

@jwilm Sorry, it happened on my laptop ASUS K501UX too.

If I switch on NVIDIA card, it works fine. Intel HD 520 not.

Quite a few laptops of simmilar vintage don't support opengl ES 3.x. Please consider whether you can make this software compatible with those machines. I can't wait to try it out!

@jwilm Any hints of what would need to be done to support GLSL 1.20, say?
kamalmarhubi
on 12 Jan 2017
@kamalmarhubi haven't looked into it at all, and I'm not that familiar with GL's evolution to know what won't be available. One thing that's for sure is the extension we are using would not be (see build.rs).

Same issue in vmware virtual machines on ubuntu 16.10.

I've looked the sources, and it's quite difficult to make it work with GLSL 120. The vertex shader can easily be translated to 120-compatible code by removing layout qualifiers and assigning them before shader linking, and changing in/out with attribute/varying. The fragment shader is more difficult, because glBindFragDataLocation​ was added in GLSL 150 and glBindFragDataLocationIndexed​ in GLSL 330 (functions which would be required to remove layout qualifiers). I think we could do it step by step, and stop when the benefit isn't worth the effort.

This might be obvious to other users of vendor-supplied drivers, but not keeping tabs on "disputed" files (ones provided by both your dist and the blob installer) can produce this error as a false positive. In my case, these were all shared libs of the libGL* variety. Basically, I'd gotten lazy in updating the "offending-files" manifest needed by my package manager's notification hook. A somewhat related discussion on libglvnd can be found here, though it doesn't focus on the dist-vs-blob clobberfest.
For anyone else potentially affected by this corner case, here's a manicured script(1)-style gist of my attempt at identifying the files and packages involved. BTW, I'm using the latest official Nvidia installer on Fedora 25.

Just want to bump this issue, it's kinda sad not to see any progress on this. @jwilm, do you take donations? Making alacritty compatible with my laptop (Thinkpad X200T) would be worth 50$ to me.

(which should have a GMA 4500MHD thing)
As with the reminder, I think the TL;DR for this feature request is ES2 (which would include just about anything, even the 3rd gen GMAs mentioned above) or desktop 2.1 (which would cut out especially mobile)
p.s. please some mod remove that overly long OT comment

On a GTX620/GF119 with the same issue. Launched in April 2012, about 6 years old so maybe I should just get a gtx1030. Would definitely chip in $25 if that would be motivating.

Ironlake is pretty unfortunate, but with some faking and tinkering here and there you should get in the neighborhood of opengl 3.2/3.3
(information OT to this issue anyway)

What's the earliest Intel GPU that is supported by Alacritty?
l29ah
on 11 Oct 2018
@l29ah There isn't any specific lowest GPU target for Alacritty. As far as I'm concerned, I'm only testing on my R9 390, so that would be the lowest GPU I can guarantee that works. But obviously much older GPUs should also work just fine.
As long as the OpenGL features Alacritty uses are supported, the GPU should work. So GLGS 3.30+ support should be present.

I'm not completely sure it's worth it. I have an old 2011 MacBook Air with an Intel HD 3000 supporting OpenGL 3.3 according to to this, and alacritty is unusably slow.
This video shows how it can render at usable speeds with a tiny window, and quickly degrades when you run it near full screen. This is just holding j in vim and you can see that the slowness is there without scrolling the whole screen. It's every keypress.
This might be a regression - I remember it working okay-ish with a build from maybe 6 months ago. Plus, ":syntax off | colorscheme default" brings it back to roughly that okay-ish performance level.

annacrombie

While it would be nice to support older machines, I don't think there's broad interest from most of the folks contributing today to invest there.
It will likely take someone who cares a lot about this feature to implement it themselves.

If I recall correctly, this was the issue that prevented me from using Alacritty on a Raspberry Pi I own. IDK if things are different now, or with the newer Pis, but this may be a motivating platform.

I know bumping this is kinda useless but I'd just like to express my desire for older GL and GLES support as well. I'd like to have some smooth terminal for my Raspberry Pi 4 :smiley:
gustafla
on 24 Jul 2019
Just because the raspberry pi has been mentioned here multiple times, I wouldn't guarantee that its tiny GPU can keep up with what Alacritty expects to have to redraw at a sufficient framerate. So even if we do support this, it might be possible that performance isn't ideal.
chrisduerr

I think support for earlier OpenGL and GLSL versions should be tracked in #128 though, so all further comments on that are likely better posted on this more specific issue.
As requested in https://github.com/jwilm/alacritty/issues/2773...
There has been a long standing issue (#128) about supporting lower OpenGL versions and I think it might be very beneficial to support at least a few more years of old GPUs
Great! For the record it isn't just about expanding in the direction of "oldness" but also in the direction of "mobileness/embeddedness". Non-desktop GPUs generally aim for OpenGL ES and have no aspirations of supporting all of OpenGL Core.
The commit which introduced this (eac9747) doesn't shed a lot of light on things
Thanks for pointing that out, though. Is @jwilm no longer following alacritty development?
I'm not very familiar with OpenGL myself
Me neither, although I have experience with extremely-low-level non-graphics GPU programming, but that's not always helpful graphics applications that can only talk to the GPU through a large and complicated OpenGL layer.
I'm not very familiar with OpenGL myself and haven't written this code, but it seems like this separate alpha blend mask is necessary for the OpenGL blend function extension in use by Alacritty.
If you take a look at c70acba
Thanks for pointing to that, really useful to see what the shader looked like before it used Dual source blending -- that's the feature that I had to remove from the fragment shader in order to make it work on OpenGL ES. It has only been in OpenGL core since 3.3 and has never been part of OpenGL ES; not clear if it ever will be.
Basically it looks like the author of c70acba previously had a hand-written shader and found a way to make one of the advanced blending modes in OpenGL Core 3.3+ do the same thing his hand-written shader was doing. So the shader went from being 7 lines of code to 2 lines of code at the expense of only working on desktop GPUs.
Would it be a maintainability nightmare to have two sets of shaders? If not, I can prepare a patch which will basically amount to restoring the old shader within an "if OPENGL_ES { ... }" block.

At the moment only very, very intermittently. So I wouldn't expect any response.
Would it be a maintainability nightmare to have two sets of shaders? If not, I can prepare a patch which will basically amount to restoring the old shader within an "if OPENGL_ES { ... }" block.
I think multiple shaders would significantly impact maintainability especially if one of them is rarely ever used. If you've already had trouble understanding what our two shaders were used for, having three isn't going to make anything better.
Restoring the old shader would also undo all the benefits we gained from it, which were not only the removal of a few lines of code. So I'm unsure if we want to make a gimped version of Alacritty available for older platforms.
chrisduerr
on 3 Sep 2019
GL_EXT_blend_func_extended allows dual source in ES.
And it's also supported in mesa.
Freedreno should already have it for example.
I'm not sure why r300 or <Gen6 (some of the "critical" hardware in this thread) don't support it though.

Bump. I know that for the alacritty devs, their GPUs support these features, which makes this issue easy to forget about. But a lot of us are on older hardware, ARM boards, etc - and this would really be a boon for us. Please consider looking into this issue.
ddevault
on 10 Dec 2019
While I'd love to solve this issue, it's likely one that will take a lot of effort without reaping a ton of benefits.
I don't think I have access to any hardware that doesn't support Alacritty's OpenGL requirements, even my proxmox virtualization on an ancient HP server seems to handle it just fine. So I'd likely have to look into software solutions to try and emulate this, which would likely cause a bunch of work just to try and reproduce this.
The OpenGL code is also something I'm not very familiar with. While I have written some of the shaders and OpenGL code, I have absolutely no clue about the differences between the various OpenGL versions, so after being able to reproduce, it would likely still be a long way out just to identify which of the issues actually causes Alacritty's incompatibility.
In a perfect world, after having identified the problem, we'd just replace one OpenGL call with another and maybe be good to go without much work. But Alacritty uses some OpenGL features which I'd classify as not extremely common, so I think that it would also be possible that this requires a large overhaul of our rendering, plus shaders. Which would of course be a big chunk of work.
Then there's the additional problem of making sure that this doesn't get destroyed in the future. The emoji support for example will require big changes to the rendering and without a system to easily test things on, it's not unlikely that systems with insufficient OpenGL versions will continuously find issues even in our public releases.
Of course none of this is a reason why we wouldn't implement this. These are just the reasons why it would be a lot of work and there are of course a lot of other issues which are less work and provide more benefit to a larger audience of users. I can't even say if Alacritty performs sufficiently well on that old hardware, or if we'd have to write a second non-opengl frontend just because that's faster on ancient GPUs.
Until now, I've mainly been hoping someone else with OpenGL experience would want to pick this up to play around with things, but that hasn't happened in almost three years so I'm not very hopeful that's going to change anytime soon.

Assuming that is an environment variable, it does not prevent Alacritty from launching.
chrisduerr
on 11 Dec 2019
Summary of findings so far:
- The hardest pill to swallow will be that instanced rendering needs to be refactored out. We need to just draw each cell in a loop on the CPU.
- VBOs/IBOs have to be removed.
- Converting the shaders to a lower GLSL version is reasonably easy.
ddevault
on 12 Dec 2019
Alternative to drawing every cell in a CPU loop, we could probably arrange the batch as a single triangle strip.
ddevault
on 12 Dec 2019
After some discussion in IRC, it seems like the best way forward with this issue would be to investigate https://github.com/gfx-rs/gfx, since that advertises OpenGL 2.1 support (probably the right minimum version), and would also give us a path forward to a post OpenGL world.
This is by no means a small task, but could lead to better hardware support overall.
nixpulvis
on 12 Dec 2019
I'd like to add, that there's not an insignificant risk with impacting existing OpenGL 3.2+ systems, which obviously should be completely avoided.
I remember in the past that even minor tweaks to the instance data setup could have noticeable impact, so I'm uncertain if getting rid of that completely is a viable solution or if that will negatively impact performance on existing setups.
chrisduerr
on 12 Dec 2019
A more conservative option would be to fork the renderer entirely, then ship with two renderers - picking the best supported one. Then the GLES2 compatible renderer wouldn't have to impose any limitations on the OpenGL 3.2+ renderer.
ddevault
on 13 Dec 2019
@ddevault we discussed this a bit as well, and while I may agree for the purposes of prototyping it, it's going to be hard to maintain two separate versions of the renderer. This is why I'm hoping something like gfx could be the solution. If the performance is comparable, and the code isn't too crazy I think it should be.
I suppose I'm assuming that we can't achieve the same level of performance with OpenGL < 3.3 on modern hardware, but I do not have data to support this assumption at this time. Maybe someone else can shed some light on this?
Either way, I think we should start looking into #183 at some point. This issue is good to keep in mind.
nixpulvis
on 13 Dec 2019
I think we can get comparible performance, but only with a total overhaul of the renderer.
ddevault
on 13 Dec 2019
Assuming that is an environment variable, it does not prevent Alacritty from launching.
That's because it doesn't affect desktop GL, which I guess alacritty uses by default (or exclusively)?
GLES 2.0 is probably the lowest target one may want to reasonably target though, so testing would find that useful.

Looks like there's some hope for users of ARM Midgard (and newer) GPUs with the upstream Panfrost Mesa driver. They just experimentally opened debug access to GLES 3.0 spec on Panfrost. GLES 3.0 uses GLES shader level 3.00 which is based on GLSL 3.30!:
https://www.collabora.com/news-and-blog/blog/2020/02/27/experimental-panfrost-gles-3-support-has-landed/
I immediately tried to run alacritty after compiling and setting the requisite environment variable to expose the GLES 3.0 bits and alacritty crashed. No doubt the crash is caused by the panfrost driver since it's still experimental and hasn't got all the bugs worked out yet (they also may still be implementing core features.) But when their ES3.0 is ready for primetime, we may have low power boards capable of running alacritty!

For anyone interested, I threw together a quick port to GLES2. It's working okay on my X200. Branch is here: cyclopsian/alacritty#gles2.
cyclopsian
on 14 Mar 2020
@cyclopsian Thanks a lot for your work. Your fork runs on the RPi 4, in sway, as smoothly as konsole (my second-favorite terminal because it feels more responsive than gnome/lx/xfce-terminals). Not quite full framerate, but much better than all my other options. This at least proves that support for low-end devices would benefit some users (I don't want to use konsole because it's slower to start up and needs qt). Also I doubt the Raspberry Pi 4's GPU drivers are fully optimized yet, so the future for alacritty on the Pi is looking good.
gustafla
on 14 Mar 2020
@gustafla The Raspberry Pi 4 actually supports GLES3 so it's not necessary to use the GLES2 branch for that. The only thing that needs to be removed there is the multisampling. I have an older GLES3 branch that was quickly hacked to work, but I never bothered fixing the colored emojis for it: cyclopsian/alacritty#gles3.
cyclopsian

FYI colored emojis rendering is also broken on master. (you need dark backgrounds for them to look better).

I just built and tested this on my i.MX8M machine that has a GC7000 GPU driven by etnaviv. It can do only GLES2. And it works fine so far! Many thanks!
mntmn
on 14 Mar 2020
Thanks for your work @cyclopsian. Even though the ideal way to fix this as far as I'm concerned would probably be to make use of gfx-rs, it seems like your patch is fairly straight-forward.
If this helps with compatibility, I'm curious if there's a way we could make use of this to support older platforms on our master.
It would be interesting to see how performance of this compares to Alacritty's renderer on machines that support GLSL 3.30+. Would be nice to have feedback for different platforms too, since OpenGL support is very different between platforms.
If someone is interested in testing this, it should be compared to HEAD~1 on that branch, since master might have changed performance in other ways.
chrisduerr
on 14 Mar 2020
Can you be specific (in terms of shas) as to which commits should be compared for performance differences?
ddevault
on 14 Mar 2020
The latest version of cyclopsian's branch (https://github.com/cyclopsian/alacritty/commit/2e15b476ea1125c6fa6c0a694e8a911079577da7) should be compared to its parent (https://github.com/cyclopsian/alacritty/commit/d20051b5e5a8ee3c8dcd75a87d375ac7611a9d2d).
I've run it on my machine and I haven't been able to notice any utterly devastating performance regressions, though I would need to reboot to get reliable performance results which I unfortunately cannot do today.
But I think feedback from multiple parties with different backend and GPUs would be useful anyways, especially since platforms like macOS have shown in the past that even relatively minor tweaks to the renderer could lead to major performance fluctuations for some.
My biggest concerns are probably the additional InstanceData fields, since that has shown in the past to be very size sensitive.
chrisduerr
on 14 Mar 2020
Also in case someone interested in testing isn't familiar with benchmarking Alacritty, it should be documented in the https://github.com/alacritty/vtebench repository.
I think the only relevant benchmark here is alt-screen-random-write, since the others mostly stress things unrelated to rendering itself.
chrisduerr
on 14 Mar 2020
One more note, is also to compare render_timer during benchmarks, since parser shouldn't slow down much if you start drawing slower, but the actual rendering times could become slower. But looking in render_timer seems like a nice idea here in general.
kchibisov
on 14 Mar 2020
Yeah that's a great point, on fast platforms that do not struggle with rendering at all, the render timer is probably more useful than just timing the command. Though I'd like to know about both since platforms that do have a ton of headroom for rendering anyways might be able to take a bit of a hit without any actual performance impact.
chrisduerr
on 14 Mar 2020
For a realistic shot at merging my branch, the changes should be put behind runtime conditionals to test for GL version and extensions. The way it is now (GLES2 with no extensions) is only good for achieving maximum compatibility.
cyclopsian
on 14 Mar 2020
Yeah that sounds about like what I'd expect.
Have you actually tested which of your changes affect performance most @cyclopsian?
Also would you be willing to look into this? Even though exploring gfx-rs is probably the most beneficial solution long-term, I'd be fine with exploring simpler solutions.
chrisduerr
on 14 Mar 2020
I haven't benchmarked, this was just a hack to get it to work on my X200 because I was impatient :smiley: It's not even ideal for this hardware because the supports the necessary extensions in GL 2.1. Maybe I can look more into this later but it's working for me now just to get the program running at least.
I don't know the full implications of gfx-rs on performance with older hardware, but ~it does appear to have some of the necessary checks, such as here: src/backend/gl/src/queue.rs#L384.~ Edit: That check errors out when instancing isn't supported, so either way an additional render path will need to be present in alacritty if older hardware is intended to be supported.
cyclopsian
on 14 Mar 2020
For what it's worth: @cyclopsian's gles3 branch already runs with the latest panfrost, via PAN_MESA_DEBUG=gles3 alacritty. Haven't tested, but it feels snappy. Startup is about 80ms slower than termite, however. This is with a MALI T-860, pinebook pro.
gleachkr
on 16 Mar 2020
I've tested @cyclopsian gles2 branch on my system with AMD Rx 570, and it's 2x slower on average in terms of rendering performance: 4ms(gles2) vs 2ms(master) on ASRW benchmark - so it's a huge hit to our rendering performance. Anyway, I feel like supporting minimum version of OpenGL that gfx-rs supports(it should be OpenGL 2.1 AFAICS) could make more sense for us, since we should move to this crate either directly or to wgpu at some point.
kchibisov
on 20 Mar 2020
Just wanted to add that the GLES2 impl works great on pinebook (aarch64). It may be slower than gles3/later opengl but it's seemingly infinitely faster than CPU solutions on arm architecture. I didn't try the gles3 impl because I haven't tried to build a custom kernel yet.
I'm using the GLES2 alacritty as my main terminal for now.
derekdreery
on 22 Mar 2020
@gleachkr How did you get that 80ms figure? Just a guess but it could be the texture atlas that is causing the slow startup. It could be sped up by caching that to disk once it's built. No way to know for sure though without more precise benchmarking.
cyclopsian
on 26 Mar 2020
@cyclopsian Nothing fancy, just time alacritty -e exit vs time termite -e exit. Sorry if this is misleading, I've switched over to your gles3 branch and I'm enjoying it quite a bit. Checking now, it's about 270-300ms for termite, 300-350ms for alacritty.
gleachkr

Noticed that folks have gotten some working patches -- any plan to merge into master? Would love to get this working on pinebook.
clarfonthey
on 9 Jun 2020
I'm using the patched alacritty with pinebook pro and it works great! Much more snappy than any of the CPU based rendered terminal emulators. Would be great to get it merged. I think that there are challenges integrating the patch, making sure that newer GL versions are used if available, with the patch as a fallback.
derekdreery
on 9 Jun 2020
Those patches are both broken (text is being blended with 'wallpaper'/background, not all things are supported, that our rendering does now) and slow (2-3x slower than master). So there's no way such things could be upstream without proper rework and perf fixes.
kchibisov
on 9 Jun 2020
I would generally recommend prioritizing workitude over performance. Doesn't matter how fast it goes if it just drives straight into a wall on startup. Merge the patch which improves workitude, then work on incrementally improving the performance again.
FYI I don't think anyone actually cares about alacritty's performance above a certain threshold, it's just rendering text. So long as it can meet the monitor's refresh rate it's doing a good job, and hell, even well below it, it's fine. I'm here becasue it's lightweight, easy to configure, and has the features I want.
ddevault
on 9 Jun 2020
Doesn't matter how fast it goes if it just drives straight into a wall on startup.
Yeah, but if you merge poor solutions to a problems into your codebase it's very hard to get rid of them. It's true in general, not only to that particular problem, that's likely why it takes a lot of time to implement certain things in alacritty.
You can always maintain your own branches and rebase them from time to time.
Merge the patch which improves workitude, then work on incrementally improving the performance again.
Yeah, but they doesn't work as we know.

So long as it can meet the monitor's refresh rate it's doing a good job, and hell, even well below it, it's fine.
Yeah, and those patches will break it. Like I'm +- fine if our rendering is below 7ms. However those patches make my laptop render in ~20ms, instead of 5-6ms, which is hard to use tbqh, so they can't even make it in 16ms anymore.
Supporting older version of OpenGL is something that we'd like to have, but we'd like to have proper solution that is also maintainable and doesn't break current certain users' experience, not halfly working workarounds.
kchibisov
on 9 Jun 2020
Yeah, but they doesn't work as we know.
Yeah, agreed, they need fixin, but my point was that if performance were the only problem then that should be sufficient unless it's egregious.

I don't want to be That Guy and I know this is Your Thing, but these performance numbers are still pretty good and entirely acceptable for almost everyone. To the point where you may be suffering from the placebo effect. It's a terminal emulator.
Even so, it would be good to have two render paths to take best advantage of the hardware capabilities as possible. But be aware that the status quo freaking sucks right now. Half of my computers can't use alacritty at all without LIBGL_ALWAYS_SOFTWARE=1, and if you think your laptop performance is bad then you should try swrast on for size and see how that feels.

A condition of merging the patch in any form would be that it did not regress performance for those who can use the newer GL.

The current problem is that barely no one bothered to write proper solutions to that problem (I don't even have hardware with OpenGL less than 3.3 and never had). It's not true that we reject all the patches that are being send to us to that problem due to their perf problems, it's more like we've got ~zero patches to solve that problem. And the only patch right now is the one @cyclopsian posted here, which wasn't send to us directly to start/make review of and doesn't work at all, since it was purely to make thing start and work on one particular setup.
kchibisov
on 9 Jun 2020
So long as it can meet the monitor's refresh rate it's doing a good job
Fyi I haven't found a single other terminal emulator that can match my monitor's refresh rate of 144Hz at whatever I throw at it. Sure, 144Hz might be a bit much, but most can't even get to 60 with reasonable input (last I tested throughput, Kitty sat at ~40 for me for example).
Even if these patches were working 100%, there is no way I would merge them if the performance was that bad. A performance regression of that magnitude is far more than just a slight performance hit, it's like directly removing a feature. So the performance regression alone is a reason why these patches aren't working properly.
Really, this is mostly like supporting another platform. Currently we do not have support for previous OpenGL versions at all and that is intentional. There is no desire to ever support these if they regress master that badly. Adding them as a new platform is just something we're interested in investigating if it does not cause too many troubles.
Saying that adding a new platform is more important than keeping the old platforms working is a bit inflammatory and I don't think that approach would get us anywhere. Alacritty isn't broken, it just doesn't support these platforms by design.
chrisduerr

It won't even be an issue for pinebooks for ever, since gles3 drivers are in development. It would however be a nice project for someone who wanted to learn more about GPU development.

I just want to note that I have successfully compiled this branch based on cyclopsian's patch on my Pinebook Pro: https://github.com/nuumio/alacritty/tree/cyclopsian-gles2-nuumio
It runs great, at least as fast as Konsole when both are using gles2 to my untrained eye, i.e. not enough latency for me to notice. I'm not familiar enough with benchmarking to scientifically measure the difference. I'm not necessarily saying that you should support this platform, I too am eagerly looking forward to gles3 support.
I just don't quite understand what people mean when they say it doesn't work, it looks like it works to me. This patch made the difference between me using alacritty or not, and it helps with running e.g. sway or other wayland desktop environments that like alacritty for the terminal emulator.

Just fyi speaking of rendering, so folks stop asking 'what is not working'.
left is gles2 branch, right is master. You can see that left is pink and doesn't render certain things.
kchibisov
on 9 Jun 2020
So, I'm honestly a bit stuck on what to do here. The GLES 2 branch isn't mergeable as-is because it forces everyone to use GLES 2, but we still can't use master on hardware that doesn't support GLES 3.
Maybe the right step here is to start by updating the code to detect the what GLES version is available ahead of time and then use that to select the proper renderer? And maybe some refactoring work to start that working. An added bonus of this is we could use similar code in the future to implement a Vulkan version while not also breaking folks who don't have Vulkan-aware drivers.
Not 100% sure if I'll have the time to help out but would like to at least try to start the ball rolling for this. Although in the case of the Pinebook Pro eventually we'll have GLES 3 and Vulkan support, I think that the best plan would be to support GLES 2 as there will always be hardware that requires it IMHO.
clarfonthey
on 10 Jun 2020
Yes I think the solution would be to move the gles2 somewhere separate, and have the code fall back to using it if a more modern api isn't available. And also fix the visual artifacts above.
derekdreery
on 10 Jun 2020
As of a recent series of merges to mesa master, alacritty is now working for me on the panfrost driver! This is on a Pinebook Pro, with the Mali T860 MP4 GPU. I've been using it all day, and it seems smooth and stable. I'm running it in sway (wayland), in case that's relevant.
Setting PAN_MESA_DEBUG=gl3 is necessary, as some of the GL 3.3 functionality is not yet implemented. Note that PAN_MESA_DEBUG=gles3,gl3 is unnecessary, as the gles3-flagged behavior has now been enabled by default in master.
(Apologies if this is off-topic, but it seemed like a major recent driver of this request was ARM GPUs.)

Hi, so i found this thread because I see the same error that the op had. I run Arch linux. Does anyone else still have this issue? The workarounds mentioned in the thread did not help me...

Yes. I cannot use it on Centos 7 since the new version of nvidia drivers.
None of the workaround worked for me neither.

Wanted to add that I'm getting this on FreeBSD 12.1 when I have i915kms loaded and the Intel Xorg video driver package installed. Thinkpad T400.
Alacritty encountered an unrecoverable error:
There was an error initializing the shaders: Failed compiling shader at /usr/ports/x11/alacritty/work/alacritty-0.4.3/alacritty/../res/text.v.glsl: 0:14(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, and 1.20

@teran-mckinney seems like your GPU (Intel GMA 4500MHD) doesn't support OpenGL 3.x. Unless I've looked up the wrong parts.

I think you are right. I guess I thought it was the other way around, that makes more sense. I see Intel GM45 in dmesg. So does Alacritty only supports newer shaders then.

FWIW I've been working on a new renderer (which ended up being an almost complete rewrite), that makes supporting OpenGL ES2.0 w/ GLSL ES1.00 rather straightforward. There will be a PR in a few days. (it's also up to 20x faster in some conditions, and is never slower).
